4 Claims. (Cl. 137-69) This invention relates to improvements indetachable dispensing faucets for liquid containers of various kinds.

Many liquid products are commercially distributed in large cans, such asgallon and ilve gallon cans, and in other forms of containers. Suchcontainers are usually provided in a wall thereof with a screw-threadedor non-screwthreaded pouring neck or similar form of spout or openingwhich, with respect to the filled container, is initially closed by avremovable cap, stopper, plug or other form of closure, which must beremoved when it is desired to discharge liquid from the container.

Pouring of liquid from containers of the kind above referred to, throughthe pouring neck, spout or opening thereof, is an awkward operation,especially when the container is of large size or bulky, and frequentlyinvolves waste and loss of the liquid by reason of uncontrolled ilow,spillage and like occurrences. To obviate such inconvenience and loss,when dispensing liquid from such containers, detachable faucets havebeen heretofore provided which are adapted to be connected with thecontainer pouring neck, spout or opening. Such faucets must usually beprovided with a coupling connection which conforms to the particularstyle and size of pouring neck, spout or opening possessed by a givencontainer desired to be served thereby. By reason of this, aconsiderable number of styles and sizes of faucets and their couplingconnections are necessary if itis desired to accommodate a variety ofstyles and sizes of containers.

Having the above circumstances in view, it is the purpose of thisinvention to provide an improved detachable dispensing faucet which, byreason of the novel characteristics of the coupling connection meanswith which it is provided, may be quickly and easily operatively engagedwith a variety of styles and comparatively wide range of sizes ofcontainer pouring necks, spouts or openings.

An illustrative embodiment of this invention is shown in theaccompanying drawings, in which:

Fig. 1 is a longitudinal sectional view of a container showing a noveldetachable dispensing faucet according to this invention as operativelycoupled thereto in connection with the pouring neck thereof; Fig. 2 is ahorizontal sectional view, taken on line 2-2 in Fig. 1, but drawn on anenlarged scale; and Fig. 3l is a transverse vertical sectional view,taken on line 3 3 in Fig. 2.

Similar characters of reference are employed in the above describedviews, to indicate corresponding parts.

In the drawings, the reference character 5 indicates a container, an endwall 6 of which is provided with a pouring neck I, which may beinitially closed by a suitable removable stopper or closure means (notshown). After the pouring neck 1 is opened by removal of said stopper orclosure means, the novel detachable dispensing faucet of this inventioncan be assembled with and in secured operative relation to the pouringneck 1. A

The novel detachable dispensing faucet according to this inventioncomprises a base plate l which is preferably provided with a rearwardlyprojecting peripheral ange 9. Afllxed to and extending through andoutwardly from said base plate 8 is a faucet spout III, the inner endportion of which is flared to provide a valve seat II. Cooperative withthe valve seat II is a valve member I2. The valve member I2 is providedwith a push stem I3 which extends outwardly. through the interior of thefaucet spout I0, to project through and exteriorly from the wall of thelatter and through a tubular slideway or guide element Il which is amxedto. said wall. Ailixed to the outer end of the push stem I3 isa pushbutton or finger piece I5. The valve member I2 is yieldably closed uponthe valve seat II by the thrust of a compression spring I6 which ismounted around the external portion of the -push stem I3, between theslideway or guide element I 4 and the push button or finger piece I5.

Also affixed to the base plate 8, to open outwardly thereof, is a vacuumbreaker or air admission tube I'I. This tube I1 projects inwardly fromthe base plate 8 as at I'I'. and is then suitably bent to extendupwardly through the interior of the container 5,*when the faucet isoperatively attached to the pouring neck l, so as to terminate withinthe upper level of the container relative to the lower level thereoffrom which the attached faucet extends when the container is disposed inposition to discharge its liquid content through the faucet. The upperor free end of said tube I'I is provided with an outwardly openingball-check valve I8, which is operative to prevent entrance of theliquid content of the container into the tube I1 but which permitsdischarge of air from' the tube into thecontainer interior with vacuumbreaking effect when the valve member I2 is opened for outflow of liquidthrough the faucet. v

The means for operatively attaching the faucet to the pouring neck 'I ofthe container 5, in a prises a supporting member I9 which is affixed tothe base plate 9 to extend throughand outwardly therefrom. Saidsupporting member I9 is provided with an endwise open bore 20 which ispreferably of polygonal cross-sectional shape. and which provides aslideway in which is mounted a draw-bar 2| of corresponding crosssectional shape. This draw-bar 2| is non-rotatably supported by themember I9 subject to axial sliding movements therein relative to thebase plate 9 and parallel to the pouring neck 1 of the container whenthe faucet is attached to the latter. The draw-bar 2| is provided at itsouter end with a screw-threaded extension 22 w ch is adapted to projectexteriorly from the outer end of the supporting member I9. Threaded ontothe extension 22 is a knurled nut piece 23 which bears and thrustsagainst the outer extremity of the supporting member I9. At its innerend, the draw-bar 2l is provided with an angularly proiecting fulcrumpiece 24. Pivotally mounted on the end of the fulcrum lug 24, by anattachment screw or other suitable pivoting and attaching means 25, is aclamp-bar 29 having oppositely extending arms 21 and 29. The clamp-bar29 is biased by a torsion spring 29 to turn about its pivot in clockwisedirection, as viewed in Fig. 2. Mounted on the inward extension I1 ofthe vacuum breaker or air admission tube I1 is an abutment lug 90 whichis opposed to the arm 29 of the clamp-:bar 29.

Supported upon the inner side or face of the base plate 9 is a sealinggasket 9|, which may be made of any suitable resilient and liquidimpervious material, such e. g. as rubber.

To condition the detachable dispensing faucet, characterized as abovedescribed, for attachment to a container, the nut-piece 23 ismanipulated to move inwardly the screw-threaded extension 22 of thedraw-bar 2|, thereby sliding the latter axially inward through thesupporting member I9. Such inward movement of the draw-bar 2| moves theclamp-bar 26 away from the base plate 9, and carries the arm 29 of saidclamp-bar into arrested engagement with the stationary abutment lug 99,whereafter continued inward movement of the draw-bar and clamp-barcauses, through the arrested arm 29, a counter clockwise rotation of theclamp-bar about its pivotal connection with the draw-bar, whereby theclampbar is swung toward a parallel disposition relative to the axis ofthe faucet (see dotted position of the clamp-bar shown in Fig. 2).

After the clamp-bar 29 is initially disposed as above described, thesame, together with the vacuum breaker or air admission tube I1, can beinserted through the open pouring neck 1 of the container until thebase-plate 9 with its sealing gasket 9| abuts and bridges over the outerend of said pouring neck. When the faucet is thus applied to the pouringneck 1 and properlyA disposed in desired service relation, the nut-piece29 is manipulated to move outwardly the screwthreaded extension 22 ofthe draw-bar 2|, thus drawing the latter outwardly through thesupporting member I9, and thereby moving the clamp-bar 26 away from theabutment lug 99 toward the container wall E. As the clamp-bar is carriedaway from the abutment lug 99, the spring 29 becomes operative to rotatethe clampbar clockwise to a position transverse to the axis of thepouring neck 1 and the faucet, whereafter continued movement of theclamp-bar toward the container wall 6 finally brings the former intoengagement with the inner face of the latter and into bridging relationto the opening of the pouring neck 1 (see full line showing in Figs. 2and 3). By turning the nut-piece 29 strongly home against the end of thesupporting member I9, the clamp-bar 29 is caused to nrmly grip andthrust against the container wall 9 so asto draw the base plate 9 andits sealing gasket 9| into tightly bound engagement with the outer endof the pouring neck in leak-proof joint forming relation thereto, and atthe same time securely coupling the faucet in its operative attachedrelation to the pouring neck.

It will be understood that by reversing the above described operationsthe faucet can be readily detached from the container.

From the above it will be obvious that the novel dispensing faucet ofthis invention is well adapted, within reasonable limits, for operativeattachment to a variety of different styles and sizes of containerpouring necks and other forms of container discharge openings.

Having now described my invention, I claim:
